Answer:

i think this is the answer aha

to get from 5 to 55 you times by 11

so i think to get from 11.8 to x you do the same thing and multiply by 11.

11.8×11=129.8

so x= 129.8

i think aha

How would you find values of m for question 'b'?

Trava [24]

This is known as quadratic algebra.

To find it, you can use the quadratic formula but that might take a while.

We can factor it out and get

-3(mx² + mx - 1)

We can then set mx² + mx = 1

It would have no solutions

Edit: Above is wrong! I made the mistake of factoring 3 when it cant be factored.

Here is the solution

mx²-3mx=-3

Divide both by -3

mx²+mx=1

And I really messed this up. Its been a long time since quad. Sorry, but I cant seem to get the answer. Try and look up the quadratic formula and see if you can use that

Solve x2 = 12x – 15 by completing the square. Which is the solution set of the equation?

Nady [450]

For this case we have the following polynomial:
$x ^ 2 = 12x - 15
$
The first thing to do is to place the variables on the same side of the equation.
We have then:
$x ^ 2 - 12x = -15
$
We complete the square by adding the term (b / 2) ^ 2 on both sides of the equation.
We have then:
$x ^ 2 - 12x + (-12/2) ^ 2 = -15 + (-12/2) ^ 2
$
Rewriting we have:
$x ^ 2 - 12x + (-6) ^ 2 = -15 + (-6) ^ 2

x ^ 2 - 12x + 36 = -15 + 36
 
(x-6) ^ 2 = 21$
$x-6 =+/- \sqrt{21}$
Therefore, the solutions are:
$x = 6 - \sqrt{21}$
$x = 6 + \sqrt{21}$
Answer:
the solution set of the equation is:
$x = 6 - \sqrt{21}$
$x = 6 + \sqrt{21}$
